- tension (isometric contraction) stage -

During the tension (isometric contraction) stage,

  • the ventricle is contracting.
  • the pressure in the ventricle is higher, compared to the pressure in the atrium.
  • the atrio-ventricular valve is closed
  • there isn't any blood flow from the atrium to the ventricle.
